LAWN-SIPRINKLING DEVICE.

Specification of Letters Patent.

Patented Nov. 19, 1907.

Application filed October 15.1906- Serial No. 333,988.

ject theiprovision of means for facilitating the sprinkling or wateringof lawns and gardens.

Another object of the invention is the in1- provement of theconstruction of a device formed ofa minimum number of parts, whichdevice is comparatively inexpensive to cons'truct.

With these and other objects in view, the invention consists of certainother novel constructions, combinations, and arrangements of parts, aswill be hereinafter fully described and claimed In the drawings: Figure1 is a perspective view. of a device constructed in accordancewiththe'present invention. Fig. 2 is a vertical, sectional view of the.sprinkler-head and a fragmentary view of the support. Fig. 3 is afragmentary, perspective view of the upper portion of the support.

Referring to the drawings by numerals, 1 designatesthe vertical portionof a rod-like support, which is bent intermediate its ends and producesa horizontal, preferably rightangled,'integral extension 2. Theextension 2terminates at its outer end in an integral, annular,expansible spring-collar 3, which collar is provided at its outer freeend with an integral, flat lug 4. The lug 4 is positioned normallyparallel with a flattened portion 5 of the extension 2 of the support.The flat portion 5 and the lug 4 are apertured for receiving a threadedbolt 6, which bolt 6 is provided with a nut 7, Fig. 3. The bolt and nut6 and 7, respectively, constitute fastening-means whereby the collar maybe seoutwardly-extending, annular flange 12. A

nally threaded for receiving an ordinarv coupling device secured to theend of a hose. A flexilile washer 15 is positioned within the threadedcollar 13, and is employed for the ordinary purpose of obtaining a tightjoint, when the hose, as indicated by dotted lines 16, Fig. 1, iscoupled to said collar. The coupling-collar is capable of a slightlongitudinal movement upon the neck 8 between collar 3 and flange 12 forfacilitating the at: tachment of the hose 16 to the sprinklerhead 9;said collar 3 limits the longitudinal movement of the coupling-collar 13upon said neck 8 for pre'venting displacement of the washer 1,5. Theupper edge of the section 10 is provided with an annular flange or rim17.

The upper section 11 is perforated or apertured and is provided with anannular bead 18. Vhen the upper and lower sections are secured together,the bead 18 fits over the annular flange or rim 17, thereby fixedlysecuring the sections together. The securing of the sections together isordinarily done by machinery during the manufacture of thesprinkler-head. By forming the sprinklerhead in sections, the punchingof the apertures in the upper section is easily acco1nplished, withoutextra labor or ruining the shape of the upper section, as would be thecase if the punching of the apertures was attempted in a single-piecehead. It is to be noted that I preferably form my head of sheet-metal,as for instance, brass. Many advantages are obtained by forming the headof sheet-metal, among which may be mentioned the lightness in weight andthe ease with which the parts are manufactured and assembled.

The sprinkler-head is carried by the support by placing theclamping-collar 3 around the neck 8, and subsequently bringing the lug 4in engagement with the flattened portion 5 and securing said lug in thisposition by any suitable fastening means, as for instance, bolt and nut6 and 7, respectively. The device is then ready for use, and theoperator can secure the same in any desired position by forcing thevertical. portion of the support into the ground. The hose' 16 may beattached either before or after the device has been positioned.

What I claim is:

1. In a device of the character described, the combination of asprinkler-head support, comprising a vertical portion bent intermediateits ends and provided with an integral, horizontal extension, aspring-collar provided at one end with a flattened portion, saldflattened portion integral with the horizontal extension and theopposite end of said spring-collar left free, a sheet-metal sprinklerhead provided with a depending neck terminatlng at its lower end in anoutwardly flared portion, producing an integral, horizontal, annularflange, the neck positioned within the spring-collar, means clamping thespringcollar upon said neck, said spring-collar of less width than thelength of said neck, a

coupling-collar provided with an inwardly' extending, annular flange,positioned upon said neck between the spring-collar and theoutwardly-extending, horizontal flange of the neck, theinwardly-extending flange of the coupling-collar engaging the neck andnormally resting upon the outwardly-extending flange of the neck, saidcoupling-col lar being capable of a slight longitudinal movement uponsaid neck between the sprlng-collar and the horizontal annular flange ofthe neck, and a washer in said coupling-collar, said spring-collarlimiting the longitudinal movement of the couplingcollar upon said neckfor preventing displacement of the washer.

2. In a device of the character described, the combination with asprinkler-head support, provided with a collar, of a sprinklerheadprovided with a depending neck terminating at its lower end in anintegral, outwardlyextending, annular flange, the neck ositioned Withinsaid collar, said collar of less width than the length of said neck, acoupling-collar provided with an inwardlyextending, annular flange,positioned upon said neck between said first-mentioned collar and theoutwardly-extending horizontal flange of the neck, theinwardly-extending flange of the coupling collar engaging and normallyresting upon the outwardly-extending flange of said neck, saidcouplingcollar being capable of a slight longitudinal movement upon saidneck between said firstmention'ed collar and the flange of the neck, anda washer in said coupling-collar, said first-mentioned collar limitingthe longitudinal movement of the coupling-collar upon said neck forpreventing displacement of the washer.

In testimony whereof I hereunto my
